When monitoring the relative humidity in the data center we recommend early warning alerts at 40 and 60 relative humidity with critical alerts at 30 and 70 relative humidity.
Server room humidity too low.
Too dry will result in the build up of static electricity on the systems.
While servers will chug along just fine down to 50 f it would cost way too much money to keep temperatures this low year round.
If the humidity level is too high then the humidity will develop condensation.
Too much humidity will cause condensation leading to hardware corrosion and equipment failure.
Environments with a low relative humidity rh are more susceptible to electrostatic discharge esd.
According to movincool too much humidity in a server room can result in condensation and eventually corrosion or electrical shorts.
Our recommendations on humidity alerts remain the same as they were in 2005.
High humidity low humidity cause damage in data centre server rooms.
What is a minimum acceptable humidity for a server room and what is the best way to introduce proper humidity into the environment.
What makes humidity such a dangerous problem is its two pronged attack.
Conversely too little humidity contributes to electrostatic discharge.
Normally airborne moisture vapor works to dissipate static electricity preventing buildups that would otherwise lead to esd.
While temperature is a concern it is the humidity that can cause the most damage.
Extremely low humidity in server room rooms without computers in the same building are around 35 humidity.
That may seem rather warm to some.
Humidity the concentration of water in the air is a variable with undesirable consequences for a data center at either extreme.
When the air is dry however static electricity can travel more easily.
If humidity is too low the dry air will lead to electrostatic discharge esd which can damage critical server components.
Especially considering data center expert don beaty told data center knowledge that the average server room temperature falls somewhere between 73 and 75.
